Functional Devices RIBTD2401B Enclosed Time Delay Relay
Product Information
The RIBTD2401B is an enclosed time delay relay with a single pole double throw (SPDT) contact type and a 20 Amp continuous duty coil. It has a timing range of 6 seconds to 20 minutes and a timing adjustment of 4 position dip switch for range selection and a single-turn potentiometer for timing adjustment within range. The relay has a voltage timing variance of +1% and a temperature timing variance of +1%. It has a maximum recycle time of 750ms and dimensions of 4.00 x 4.00 x 1.80 with a .50 NPT nipple. The relay is UL Listed, UL916, C-UL, CE, RoHS approved, and is accepted for use in plenum and NEMA 1 housing.
Product Usage Instructions
The RIBTD2401B can be used for various applications that require a time delay. Below are the steps to use the relay:
- Connect the required voltage input to the coil – 24 Vac/dc or 120 Vac, 50-60 Hz.
- Select the required timing range by depressing the corresponding switch on the dip switch (1-4) as per the timing table provided.
- Adjust the timing within the selected range using the potentiometer (A-D).
- Connect the load that needs to be delayed to the relay contact as per the application example provided in the user manual.
Note:
The relay can be used for various applications such as controlling
thermostats, heaters, circulating fans, and electronic ballasts. It is
important to refer to the user manual for specific application examples and
wiring diagrams.
